Abstract
The utility model relates to a chemical oxygen consumption (COD) on-line fast detector. A sampling pipeline is connected with a sampling valve through a filter; the other end of the sampling valve is connected with a buffer; one side of the buffer is connected with a reagent discharge tube of a reagent pump. The buffer and a reactor, the reactor and a cooler, the cooler and a photoelectric detector are respectively connected by an electromagnetic valve; signals detected by the photoelectric detector is transmitted into a signal processing system to be processed. The utility model has the advantages of reliable operation, good repeatability, high accuracy and reagent saving.
Description
The utility model relates to a kind of surveying instrument, the online tacheometer of especially a kind of chemical oxygen consumption (COC) (COD).
Similar chemical oxygen consumption (COC) tester commonly used at present mainly divides two kinds: a kind of is indoor use; Generally all be the operation of hand formula, be unfavorable for monitoring at the scene.Another kind is full-automatic online use, its dynamical element, and promptly how not ideal the reliability of pump and accuracy be, causes to detect at the scene all to be subjected to certain restriction.
The purpose of this utility model is for a kind of turn round reliable, good reproducibility, accuracy height being provided, can saving the online tacheometer of chemical oxygen consumption (COC) (COD) of reagent, Based Intelligent Control.
The purpose of this utility model can realize by following measure:
The sample channel of the online tacheometer of a kind of chemical oxygen consumption (COC) (COD) links to each other with sampling valve by filtrator, the other end of sampling valve links to each other with impact damper, one side of impact damper also links with row's reagent pipe of reagent pump, all be connected with solenoid valve between impact damper and reactor, reactor and refrigeratory and refrigeratory and the photoelectric detector, the signal that photoelectric detector detects is sent into signal processing system and is handled.
The utility model has following advantage compared to existing technology:
1, sampling section of the present utility model adopts filtrator difficult stifled, reliable.
2, the utility model is reliable, and adopts photoelectric detector to detect water sample and record demonstration automatically, its favorable repeatability, accuracy height automatically.
3, the utility model utilizes reagent pump suction reagent to enter impact damper to mix with water sample, can save reagent.
4, the utility model is parallel with bypass on the measurement main road, and it is fresh to guarantee to sample.
5, the utility model volume is little, and is simple in structure, can be suitable for on-the-spot online detection.
Concrete structure of the present utility model is provided by the following drawings:
Fig. 1 is a structural representation of the present utility model
1-sample channel 2-filtrator 3-sampling valve 4-run-down pipe

The utility model 1,2 embodiment in conjunction with the accompanying drawings is described in further detail:
With reference to Fig. 1, the sample channel 1 of the online tacheometer of a kind of chemical oxygen consumption (COC) (COD) links to each other with sampling valve 3 by filtrator 2, the other end of sampling valve 3 links to each other with impact damper 5, one side of impact damper 5 also links with row's reagent pipe 18 of reagent pump 11, all be connected between impact damper 5 and reactor 7, reactor 7 and refrigeratory 8 and refrigeratory 8 and the photoelectric detector 9 with solenoid valve 6, the signal that photoelectric detector 9 detects is sent into signal processing system and is handled, and water sample is by discharging by solenoid valve 6 behind the photoelectric detector 9 again.Be parallel with bypass 10 in addition between sample channel 1 and sampling valve 3, sampling valve 3 links to each other with bypass 10 by run-down pipe 4.
With reference to Fig. 2, the Power Drive Unit of described reagent pump 11 12 links to each other with piston pump 15 on the fixed bar 14 by transmitting bar 13, the cylinder body 16 of piston pump 15 by retaining valve with suction, arrange reagent pipe 17,18 and link to each other.
Principle of work of the present utility model is as follows: after sampling valve 3 is opened, water sample enters sampling valve 3 after filtering by filtrator 2, sampling valve 3 enters impact damper 5 with water sample, in impact damper 5 water sample with from the reagent mix of reagent pump 11, the reagent water sample that mixes enters reactor 7 by solenoid valve 6, reagent and water sample reaction under the condition of heating in reactor 7, reacted water sample enters refrigeratory 8 by solenoid valve 6 and adds water cooling, cooled water sample enters in the vessel of photoelectric detector 9, after the photoelectric sensor reception by the opposite side behind the light transmission water sample, the electric signal that output detects enters computing machine and carries out the signal Processing demonstration, and water sample is discharged by solenoid valve 6; Be parallel with bypass 10 in addition on sampling valve 3, the water sample of pipeline residual enters the bypass discharge by run-down pipe 4 before the sampling valve 3.Refrigeratory 8 also can wash by water in addition.
